Question 16

What is a Bankart Lesion

Answer 16

A pocket at the front of the Glenoid forms that allows the humeral head to dislocate into it.

Question 17

What is a Hill-Sach’s Lesion

Answer 17

The lesion is associated exclusively with anterior shoulder dislocations.
When it is driven from the glenohumeral cavity, the relatively soft head of the humerus impacts against the anterior edge of the glenoid. The result is a divot or flattening in the posterolateral aspect of the humeral head.
